Title: Improvements in or relating to clutch operating mechanism for motor vehicles
IPC: B60K23/02
Filed: 1932-10-01
Abstract: 407,112. Operating motor - vehicle clutches. POLLAK, J. E., 20, Holborn, London.-(Borg & Beck Co. ; 6558, South Menard Avenue, Chicago, U.S.A.) Oct. 1, 1932, No. 27341. [Class 80 (ii).] In engine - suction servomotor gear for operating motor-vehicle clutches controlled by regulator valve mechanism including a driveroperated main valve for connecting the actuator cylinder to suction and atmosphere, a check valve to retard approach of the clutch members just prior to engagement, and a " bleed " valve controlling the final phase of approach, the three valves operate in a single cylinder or casing communicating by a passage with the actuator cylinder. The servomotor comprises a chamber 23 with a flexible diaphragm 26 connected by a rod 31 and cable 38 to the clutch pedal 21, the main valve 50 being connected by a Bowden wire 55 to a button 58 on the gear-lever 16. When, in gear-changing, the button 58 is depressed against a spring (not shown), the double piston valve 50 is raised from a stop 60 to put the chamber 23 into communication with the inlet manifold 12 by way of pipes 61, 65 and the space around the valve stem 51, so that the rod 31 is lifted and the pedal 21 rapidly depressed. On release of the valve 50, the pipe 65 is connected to atmosphere by way of a check valve 70 normally held open by a spring 78 acting on a rod 74. The rod 74 is connected through an adjustable spring 81 to an arm 44 moving with the rod 31, so that, when the compression of spring 81 overcomes the tension of spring 78, the valve 70 closes, air then flowing in to complete the clutch engagement through a " bleed" aperture adjusted by a screw 85. The valve casing 47 is bolted at 49 to the diaphragm casing 23, which is supported by a bracket on the dash 20.

Abstract: 489,822. Tanks; valves. JONES, G. A. Oct. 15, 1937, No. 28149. Convention date, Nov. 25, 1936. [Classes 69 (i) and 135] A floating roof for tanks for storing inflammable liquids is formed of rigidly connected contiguous compartments or cells closed at the top and sides but open at the bottom. The roof shown is divided into such cells by main radial ribs 2, short radial ribs 5, and transverse partitions 3, 3a, the latter being formed by turneddown edges of the metal sheets forming the deck of the roof. The roof-joints are all welded, the ends of the ribs 2 being welded to a central dip-tube G and to discs 4, 9, which form central junction plates. A seal is provided between the roof and the tank wall by hair, fibre, bristle or other brushes 11, Fig. 3, set in two or more rows in stocks 12 having mitred &c. ends to form gas-tight joints when secured in a continuous ring round the skirt 7 by fixed and removable clips 14, 15. Between the rows are fixed metal or fabric diaphragms 13 with contacting or overlapping ends, and the tops of the brushes are protected by similarly arranged sheets 14a of bronze gauze. When lowered, the roof is supported on brackets 18, and, when it is over 30 feet in diameter, by means of hydraulic supports D comprising cylinders secured to the roof and having down wardly projecting rams which contact with stools 25 attached to the tank bottom. The cylinders are connected to a chamber F in which an air pressure is maintained above the liquid. To allow the air pressures in the cells 2 of the roof to be tested and adjusted, each cell is connected by a tube 47 to one of a series of ports arranged in one or more circular rows on the seat 43 of a valve, shown in Fig. 8. Rotation of a ported valve disc 41a allows any selected cell to communicate with a manometer 48 to indicate the pressure, which may be adjusted by admission of air through a valve 49.
